How to say "I love you, dad!" in Italian

In Italian, there are two different phrases that equate to the English "I love you" and learning how they differ is very important.

Ti amo is mainly used towards someone with whom you have a romantic relationship.

Ti voglio bene places emphasis on the tender feelings you have for the other person, without any sexual or deeply romantic undertones. It is used a lot towards family members.

For this reason, the phrase "I love you, dad" best translates as "Ti voglio bene, papà" in Italian rather than "Ti amo, papà".

One exception: It is not uncommon for parents to say ti amo or ti amo tanto to their kids, especially if they are very young.
